Lawyer would be a great resource for thinking through this.This isn't enough information to comment on tax advantages/disadvantages of an investment partner - more detail is needed. 

There may be a PM organization you can file a complaint with but only a lawyer could tell you if a suit against the PM makes sense.

They used to list agents, accountants, and lawyers, but it seems they now only list agents.In addition to those shown for Greece, you might try some of the other international brokers such as CBRE and Christies.

The lawyer should be able to clearly explain the benefits of two trusts to your family.

I'm considering paying a lawyer to do a title search.  

To a lawyer there may be a difference.

My husband is a realtor and works The área with a very reliable lawyer which is essentially what you need.

While I’m no fan of realtors, and think they are often overpaid and under qualified, the idea about not being tied down is one of the dumbest compliant’s, in literally every other line of work, you get tied down, go hire a lawyer, you pay them by the hours, go hire a doctor you pay them by the hour, and you are not being tied technically, you could agree to pay two agents out of pocket, but of course no one does this for the same reason no one pays two lawyers.  

Generally speaking, this is exactly how it worked out for us: our rents are always on the top end of the market, we have very little turnover, and our tenants tend to be young professionals (doctors, lawyers, etc.), so we have zero hassles, with very few repairs during/post occupancy.  

I tell them if I evict them, I will attempt to garnish future wages for any monies owed including the cost of the eviction and that good eviction lawyers are not cheap.
